Here are all the locations where you can find Rifts/Portals in the new season 5 map in Fortnite. These Rifts teleport you into the air and make for a perfect escape plan when you are chased. The other use is to simply use them to travel fast around the map.
After you use them they will disappear after a few seconds, so the person that is chasing you has to be quick. The map in the video was created by ImMarksman. All credit to him for the work and thanks for allowing me to use it here.
